Keep at it guy,it is definitely better for your health.
I have been vaping for just over a year,down to the lowest strength Nicotine,in my chosen e juice.
I have no interest in Rhubarb and custard and all the other flavours,I just wanted something that tasted like the tobacco that I used to smoke.
I keep two packets of (untouched)Baccy at hand to tempt me,and hope to throw them and the e stick on the fire soon.

On the battery front,I tired of spending out on ecig specific batteries,which failed after a few weeks.
I cobbled together a "red-neck" version,using a battery carrier and a push to make switch from Maplin,and the tank connector twisted from the top of a defunct battery.
For irony I housed it in a cut down cigar box.
It runs on regular rechargeable NIMH batteries,and quality ones of those are available at a reasonable cost.
I use an Evod glass tank,and replacement atomisers,available from the above link,and the battery pack accepts Ego and 510 tanks,carts.
I'll post a stripped down pic.
It is amusing to watch peoples faces when I use it,most think I am using a Walkie Talkie!
